Justun Chang

Justun Chang serves as a Contract Specialist at the General Services Administration’s PBS R10 Auburn Field Office, where he plays a pivotal role in executing strategic real estate and facility infrastructure acquisitions across the Pacific Northwest. Responsible for managing the full lifecycle of federal construction and modernization contracts, Chang ensures compliance with FAR regulations while advancing the agency’s mission to deliver secure, efficient, and sustainable government workspaces. His procurement portfolio is centered on commercial and institutional building construction, encompassing new builds, renovations, and systems upgrades to support federal tenant agencies. He works closely with project managers, architects, and engineers to align contracting strategies with facility operational requirements and sustainability goals. Chang cultivates collaborative relationships with a diverse pool of contractors specializing in federal construction, including general contractors, specialty trade firms, and design-build teams. While no single vendor dominates his portfolio, he consistently engages with firms possessing demonstrated experience in public-sector construction, safety compliance, and federal facility standards. His approach emphasizes transparency, competitive bidding, and performance-based contract management to ensure quality outcomes and accountability. A staunch advocate for small business participation, Chang prioritizes socioeconomic set-asides, with 50% of his acquisitions designated for total small business set-asides under FAR 19.5 and an additional 25% reserved for service-disabled veteran-owned small businesses. This reflects a deliberate strategy to foster economic inclusion and expand contracting opportunities for underrepresented entrepreneurs in the construction sector. His primary technical focus is on NAICS 236220—Commercial and Institutional Building Construction—where he procures comprehensive construction services including structural work, HVAC modernization, electrical systems, and accessibility upgrades. Chang’s expertise lies in translating facility needs into technically sound, compliant solicitations that attract qualified bidders while ensuring adherence to federal building codes and energy efficiency standards.
